This mirror was adapted from an Empire period bronze thermometer - almost certainly of French origin. The design elements relate to sun and water - and - thus - to temperature. Mermaids were the descendants of Neptune and Amphitrite - a sea nymph: their use in neo-classical ornamentation is widespread. The sun face at the top is reminiscent of the emblem of Louis XIV of France - the "Sun King," who embellished his "converted hunting lodge," Versailles - with this image. 7 1/4" high.
French ca. 1820
